Excoriation disorder

Excoriation disorder, more commonly known as dermatillomania, is a mental disorder on the obsessive–compulsive spectrum that is characterized by the repeated urge or impulse to pick at one's own skin, to the extent that either psychological or physical damage is caused. The exact causes of this disorder are unclear but are believed to involve a combination of genetic, psychological, and environmental factors, including stress and underlying mental health conditions such as anxiety or obsessive-compulsive disorder (OCD). Individuals with excoriation disorder may also experience co-occurring conditions like depression or body dysmorphic disorder (BDD). Treatment typically involves cognitive behavioral therapy and may include medications. Without intervention, the disorder can lead to serious medical complications.
